They don't mean me.
Sometimes warning signs are for everybody.
This one was at Hopewell Rocks, a provincial park in New Brunswick where the tides of the Bay of Fundy are at their highest. You can walk up to the sign at low tide.
This was way before high tide.
You can walk on the ocean floor at low tide and then watch it come up 35-45 feet.
As usual on this trip it was foggy.
